Find the seventh term of the geometric sequence 1, 2, 4, ... and the sum of the first seven terms. t7= S7=
IrinaK [193]

Answer:

Seventh term is 64

Sum of the first seven terms is 127

Step-by-step explanation:

The common ratio is 2

a_{n}  = a_{1} r^{n - 1}    

n = 7 and the first term is 1.  So,

a_{7}  =  1(2^{7 - 1} )  = 2^{6} = 64

Seventh term is 64

S_{n}  =  \frac{a_{1} (r^{n} -1)}{r - 1}

S_{7} = \frac{1(2^{7} -1)}{2 - 1}

    = \frac{128 - 1}{1} = 127

Sum of the first seven terms is 127
